All piping should be thermally insulated,
especially the pipes connecting the Heat
Pump and the Pilot.

• Install the filter valve on the water inlet of the Heat Pump.
• Install the Tee with a manual purger onto the water outlet of the Heat Pump.
• Install the two Ø30mm flexibles hoses with a minimum length of 1.5m each, directly on the water inlet and outlet points of
the Heat Pump (outside of the building).
• Carefully thermally insulate the flexible hoses to limit heat losses.
• Take care not to bend the hoses more than 240mm to prevent damage to the hoses or any pinching of the hoses.
These hoses serve to decouple the Heat Pump from the rest of the hydraulic installation (
MUST
be connected due to the
Heat Pump being mounted on shock-absorbing feet).
The Heat Pump is equipped with a water
pressure relief valve set at 2.5 bars. A service
pressure below this value should be maintained.

In order to ensure that fluids can circulate properly, it is advisable to check that the sizing of piping in the circuit between the Heat Pump
and the Pilot is appropriate.
